Starting point: August 2023
On 18 August 2023 a jury at Manchester Crown Court returned guilty verdicts on seven counts of murder and seven of attempted murder. Three days later, Mr Justice Goss imposed a whole-life order. The convictions were based on the evidence adduced at trial — principally Dr Dewi Evans’s causation testimony, the shift-rota chart, the Roche insulin immunoassay result, the handwritten “confession” notes, and specific witness accounts including Dr Ravi Jayaram’s on Child K.
Some independent critique was in public circulation at that point — including early statistical commentary from the Royal Statistical Society. But the body of specialist medical critique was thin. Most of what is now public had not yet been published.
Autumn 2023 to spring 2024: the first wave of critique
- RSS commentary (Sep 2023). The Royal Statistical Society publicly raised concerns that the shift-rota chart was constructed in a way inconsistent with its published post-Sally-Clark framework.
- Private Eye coverage (continuous). Dr Phil Hammond’s “M.D.” column began sustained coverage of the medical-evidence concerns.
- Prof. Richard Gill’s lecture (Mar 2024). “A tale of two Lucies” set out the structural parallel to the Lucia de Berk case and applied the Dutch statistical critique to the Letby evidence.
- Rachel Aviv in The New Yorker (13 May 2024). The most comprehensive international long-form investigation of the case to date — and, during the Child K retrial, geo-blocked to UK readers.
Summer 2024: the retrial and the Commons intervention
- Court of Appeal refusal (24 May 2024). Leave to appeal refused on the specific grounds then advanced. Crucially, this judgment pre-dates the Shoo Lee Panel report and the majority of the subsequent independent expert reports.
- Child K retrial (June–July 2024). Retried on the single count the first jury could not agree; convicted 2 July 2024.
- Rob Rinder KC public intervention (Sep 2024). First sustained public statement of concern from inside the active criminal Bar.
- Guardian investigation (10 Sep 2024). Major investigation documenting superbug outbreak, doctor shortages, and unit designation mismatch at the Countess of Chester.
- Thirlwall Inquiry opens (10 Sep 2024). Public inquiry into institutional response begins.
- Sir David Davis MP Commons adjournment debate (Nov 2024). First senior parliamentary intervention.
Winter 2024 to spring 2025: the Panel and its successors
- Shoo Lee Panel report (3 Feb 2025). Fourteen international neonatologists, paediatric pathologists and specialists publicly conclude there is no medical evidence of deliberate harm in any of the reviewed cases.
- Bar Council letter (Apr 2025). Senior barristers and legal academics coordinate a letter in The Times calling for urgent CCRC review.
- Joint Expert Witness Insulin Report (May 2025). Independent endocrinologists and clinical biochemists specifically address the insulin evidence on Babies F and L.
- Panel Additional 10 Cases report (Jun 2025). Extended review reaches the same conclusions as the February report.
Summer 2025: institutional consequences
- Three executives arrested (Jul 2025). Cheshire Police arrest three former Countess of Chester senior executives on suspicion of gross negligence manslaughter in connection with the same deaths Letby was convicted of.
Autumn 2025: the formal CCRC application
- Mark McDonald KC files CCRC application (Oct 2025). Accompanied by more than thirty-one independent expert reports covering neonatology, paediatric pathology, clinical biochemistry, physiological modelling, statistics, infectious disease and post-mortem radiology.
- Lord Sumption and Peter Hitchens public interventions (Nov 2025). Former Supreme Court Justice publicly calls for review; Mail on Sunday columnist continues sustained broadsheet coverage.
- Anonymous Hummingbird whistleblower report (Dec 2025). 150-page document on how Operation Hummingbird was framed from the outset by the Beverley Allitt analogy.
What this arc shows
The body of evidence now before the CCRC is materially different from the body of evidence before the original jury. The difference is not a reinterpretation of the same facts. It is:
- Fourteen-international-expert medical review that did not exist in 2023.
- Independent endocrinology and biochemistry reports on the insulin strand.
- Physiological modelling on insulin plausibility.
- Statistical critique from two senior UK statisticians (Gill and Green).
- Paediatric pathology re-reading of the post-mortem material.
- Institutional-record documentation via the Thirlwall Inquiry.
- A parallel criminal investigation of the Trust’s own executives.
The CCRC’s statutory “real possibility” test is met, on a plain reading, by any of these strands individually. Read together, they constitute the most substantial body of post-conviction evidence in an English murder case in living memory.
Why 2023 cannot be “settled”
A verdict delivered on a body of evidence is a verdict on that body of evidence. When the body of evidence changes — when fourteen senior international specialists, the Royal Statistical Society framework, and thirty-one expert reports all enter the record — the criminal-justice system’s answer cannot be to say that the earlier verdict is beyond re-examination. The CCRC exists precisely for this situation. The October 2025 application is that mechanism being engaged.
